CPT® Code 38770

The CPT® Code 38770 refers to a surgical procedure known as pelvic lymphadenectomy, which involves the removal of lymph nodes located in the pelvic region. This procedure specifically targets the external iliac, hypogastric, and obturator nodes and is classified as a separate procedure. During the operation, an incision is made in the abdomen; however, the peritoneum, which is the lining of the abdominal cavity, is not opened. The surgical team carefully explores the pelvic lymph nodes on the side of the malignancy, ensuring that critical structures such as the genitofemoral nerve and the psoas muscle are preserved to prevent complications. The fatty tissue surrounding the mid-portion of both common iliac vessels, as well as along the internal and external iliac vessels, is meticulously stripped away to access the lymph nodes. The excised iliac, hypogastric, and obturator nodes are then sent for pathological evaluation, which is separately reportable. Finally, the abdominal incision is closed in layers to promote proper healing and recovery.
